An LCD(Liquid Crystal Display) device and a gate driving circuit thereof are provided to reduce manufacturing cost of the LCD device by reducing the number of signals required for generating a gate driving signal. A gate high voltage is applied on a first switching element(S11), which is driven by a gate start pulse of the previous gate driving signal. A gate low voltage is applied on a second switching element(S12), which is driven by a gate driving signal. One end of a first capacitor(C11) is connected to the first switching element to form a first node, while the other end thereof is connected to the second switching element to form a second node. The gate high voltage is applied on a third switching element(S13), which is driven by an output from the first node. One end of a second capacitor(C12) is connected to the first node, while the other end thereof is connected to the gate low voltage. An output from the third switching element is applied on a fourth switching element(S14), which is driven by a first or second driving signal. A fifth switching element(S15) is connected between the first node and the second capacitor. A sixth switching element(S16) is driven by the gate start pulse signal. A seventh switching element(S17) is driven by a driving signal of a next gate line. A third capacitor(C13) is connected to the third node and the gate low voltage. An eighth switching element(S18) receives the gate low voltage and is driven by the output from the third node.
